Rearrange the standard form of the equation below into y = mx + b by isolating y. <br> 5x − 2y = 6
Minchanka [31]

Answer:

y = \frac{5}{2} x - 3

Step-by-step explanation:

5x - 2y = 6 ( subtract 5x from both sides )

- 2y = - 5x + 6 ( divide through by - 2 )

y = \frac{5}{2} x - 3 ← in slope- intercept form

<h2>Writing an Equation of a Line in Slope-Intercept Form</h2><h3>Answer:</h3>

y = [ -2 ] x + [ 1 ]\\

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this Question to know more about Slope-Intercept Form: <u>brainly.com/question/24599351</u></em>

We must first find the slope.

<em>Please refer to my Answer from this Questions to know more about Slopes of a Line:</em>

  • <em><u>brainly.com/question/24640665</u></em>
  • <em><u>brainly.com/question/24638053</u></em>

We can see the marked points, (0,1) and (4, -7), are on the line.

Solving for the slope:

m = \frac{y_2 -y_1}{x_2 -x_1} \\ m = \frac{-7 -1}{4 -0} \\ m = \frac{-8}{4} \\ m = -2

Now we can now solve for the y-intercept.

<em>Please refer to the second paragraph of my Answer from this Question to know more about y-intercepts: <u>brainly.com/question/24606058</u></em>

We can see that the line intersected the y-axis at (0,1) so b = 1.
